SIST EN 300 373-1 V1.2.1:2003 is the Slovenian adoption of ETSI EN 300 373-1 for maritime mobile transmitters and receivers used on ships in the MF and MF/HF bands. It specifies technical characteristics, measurement methods, environmental tests, EMC tests, and transmitter and receiver performance requirements for equipment used in the Maritime Mobile Service, especially shipborne radio installations covered by SOLAS and the Marine Equipment Directive.
What does SIST EN 300 373-1 V1.2.1:2003 specify?
SIST EN 300 373-1 V1.2.1:2003 sets minimum requirements for radio transmitters and receivers for ship use in the MF only or MF/HF bands allocated to the Maritime Mobile Service. It covers equipment intended for SSB telephony and DSC, plus interfaces to related equipment such as external DSC encoders or decoders.
The document is organized into:
- scope and references
- definitions, symbols and abbreviations
- general requirements
- test conditions and general conditions of measurement
- environmental tests
- emissions tests
- immunity tests
- transmitter requirements
- receiver requirements
- Annex A and Annex B
| Annex | What it covers |
|---|---|
| A | Normative IEC 61162-1 Frequency Set Information (FSI) command protocol for setting and reading frequency, mode and transmitter power level |
| B | Informative bibliography of related standards and recommendations |
The scope also states that EMC requirements are intended for marine environments, that EMC compliance does not by itself mean safety compliance, and that ancillary equipment is not tested as a stand-alone product.
What are the key requirements of SIST EN 300 373-1 V1.2.1:2003?
Construction, interfaces and operation
Clause 4 requires ship-suitable mechanical and electrical design, accessible maintenance points, clear labels, antenna static protection, and an antenna matching device that is automatic or simple to operate. In practice, this means the radio must be installable, serviceable and usable on a ship without awkward access or unclear controls.
Clause 4.1.6 sets the main audio and digital interfaces, including 600 Ω earth free audio paths, microphone input, loudspeaker and earphone outputs, and IEC 61162-1 control interfaces. For a buyer or integrator, this tells you what external connections the equipment must support.
Control, labeling and safety-related provisions
Clauses 4.2 to 4.4 require clearly identified controls, quick frequency changes, single-control selection of emission class, clearly marked distress controls, and protection against misuse. The equipment must also resist transient voltage changes, accidental polarity reversal and excessive voltage, and user-programmable memory must survive at least 10 h of power interruption.
Frequency coverage and emission classes
Clauses 4.5 and 4.6 cover the supported emissions and bands: J3E for SSB telephony and F1B or J2B for DSC, over 1 605 kHz to 4 000 kHz and 4 MHz to 27,5 MHz as applicable. This matters because it defines the operational range and the signalling modes the set must handle.
Test conditions and EMC methods
Clauses 5 to 9 define how compliance is checked. They set normal and extreme temperature and supply conditions, artificial antennas for transmitter and receiver tests, measurement uncertainty rules, and the EMC and environmental sequence. The environmental and EMC checks include vibration, dry heat, damp heat, low temperature cycling, corrosion, rain, conducted emissions, radiated emissions, ESD, RF fields, fast transients, conducted disturbances, power dips, failures and surge.
Transmitter performance
Clause 10 covers frequency error, output power, intermodulation products, unwanted frequency modulation, audio input sensitivity, carrier suppression, continuous operation and antenna fault protection. For example, the transmitter must stay within the frequency and output-power limits under normal and extreme test conditions, and it must survive open-circuit and short-circuit antenna conditions without damage.
Receiver performance
Clause 11 covers receiver output power, frequency error, pass band, maximum usable sensitivity, adjacent signal selectivity, blocking, intermodulation response, reciprocal mixing, spurious response rejection, harmonic content, AGC efficiency, AGC time constants, and input-circuit protection. In practice, these clauses show how well the receiver hears wanted signals, rejects interference, and keeps working in shipboard conditions.
What terms does SIST EN 300 373-1 V1.2.1:2003 define?
- Ancillary equipment - Equipment used with the radio to add control or operational features, but not needed for basic transmit/receive function.
- Assigned frequency - The centre of the frequency band assigned to a station.
- Carrier frequency - The frequency to which the transmitter or receiver is tuned.
- AGC (Automatic Gain Control) - Receiver control that helps keep audio output stable as input level changes.
- DSC (Digital Selective Calling) - The digital calling method used for maritime signalling in this standard.
- J3E - SSB telephony with a suppressed carrier.
- F1B - Frequency Shift Keying used for DSC with the stated shift and baud rate.
Who uses SIST EN 300 373-1 V1.2.1:2003?
SIST EN 300 373-1 V1.2.1:2003 is used by manufacturers of shipboard MF and MF/HF radios, EMC and radio test laboratories, conformity assessment bodies, and marine equipment engineers. It is also used by quality managers, buyers and shipyard installers who need to check that equipment fits the intended shipboard application and interface requirements.
The standard is especially relevant where equipment must support SOLAS-related ship installations, the Maritime Mobile Service, and DSC operation.
What changed in SIST EN 300 373-1 V1.2.1:2003 from the previous edition?
SIST EN 300 373-1 V1.2.1:2003 is described as a general revision in the light of Directive 1999/5/EC. It also refers to requirements from ETS 300 373. The history shows earlier publication as ETS 300 373, an amendment in 1997, and this V1.2.1 publication in 2002.

What does the SIST EN 300 373-1 V1.2.1:2003 document contain?
The document contains detailed clauses for construction, controls, labels, power and memory protection, band coverage, and warm-up behavior. It also includes measurement setups for artificial antennas, test signals, and EMC monitoring during transmit and receive testing.
It provides tables for distress frequencies, measurement uncertainty, and several transmitter and receiver limit values. Annex A gives the IEC 61162-1 FSI sentence format and field rules for frequency, mode and power settings.
